In order to maintain 10o this relation and to permit of an axial movement of the wheel 8 to and from the wheel 7, theteeth 17 on the former are elongated.

Aplate or bar 18 is supported by the rods 12 and provides bearings for a horizontal rockshaft 19, the end of which extends out through the casing 1. A lever or handle 20 is rigidly connected to the shaft 19 and is arranged to partially rotate the same when depressed. Stops 21 21 are provided on the side of the casing to limit the play or movement of the handles.

At the inner end of the shaft 19 is a crank 22, which is connected by a link 23 with a stud 24 on the plunger 11, so that when the lever 20 is depressed the plunger will be raised and by such movement the type-wheel 8 forced up into contact with the wheel 7, the raised type on the one being caused to enter the corresponding matrices in the other.

A spiral spring 26 is connected by one end to the stationary frame and by the other to the end of an arm 25, extending from the shaft 19, and tends to draw down the plunger 11 and separate the type-wheels when the lever 20 is released.

The strip or tape 32 to be punched or embossed is led from a suitable receptacle through an opening 84 in the bottom of the case 1 and is carried over an idler 27, from which it passes between guides to a feed-roller 28 and a pressure-roller 29. The latter is journaled in a pivoted arm 30 and is held in contact with the feed-roller by the pressure of a flat spring 31. After leaving the feedrollers the tape passes through a cutter and then between the two type-wheels 7 and S.

The feed-roller is operated by the following mechanism: On the shaft which carries the feed-roller is a ratchet-wheel 33, with which engages a pawl 34, which is pivoted between two fiat plates and 36,suspended from and free to oscillate about the shaft carrying the ratchet-wheel 33. A roller 37 is mounted on the stationary frame which supports the ratchet 33, while a second roller 38 is mounted between the plates 35 and 36. These two rollers are normally held in contact by the action of a spiral spring 39,which is connected with the stationary frame and the swinging plate 35, respectively. These rollers are adapted to be forced apart by a finger 40, pivoted to a stud 41 on the plunger 11 and carrying a pin 42, which engages with a curved slot in plate 35. When the plunger is raised, the finger passes up between the two rollers, and as the roller 38 is fixed the other is moved to one side. This swings the plates 35 and 36 about their pivotal axis, thereby forcing the pawl 34 forward and ad vancing the ratchet-wheel 33 and feeding the strip 32. When the plunger is lowered on the release of the lever 20, the finger 40 is withdrawn from between the rollers 37 and 38, so that the plates 35 and 36 swing back under the action of the spring 39 to their normal position.

It will be understood from the above description that when the desired type has been set or brought to the impression-point the lever 20 is depressed to emboss the character in the strip and that this operation effects the necessary feed of the strip, the devices being so rotated that the strip is fed forward during the upward movement of the plunger 11 before the two type-wheels have come into contact.

In order that each type shall be set in exactly the proper position and the two typewheels brought into perfect registration before an impression is obtained, a key-bar 43 is mounted in stationary guides 44 and caused to engage with the teeth of the index-wheel through the instrnmen'tality of a lever 45, pivoted to the stationary plate or bar 18 and operated by the plunger 11. The upper or free end of the lever 45 is formed with a knob or rounded portion which engages with a notch or slot in the key-bar 43.

v The plunger 11 carries a stud or roller 46, which passes through a diagonal slot in the lever 45. This slot is so formed that when the plunger is raised by the operation of the lever or handle 20 the roller 46 will by reason of its engagement in the diagonal slot force the upper end of the lever 45 toward the typewheels.

The upper surface of the index-wheel 4 is formed with radial slots or grooves, corresponding to and in line with the spaces between the gear-teeth, as shown in Figs. 2, 5, and 6. key-bar 43 is cut away, leaving a pointed rib 47, which when the said bar is forced forward by the lever 45 enters one of these grooves. The ends of such portions of the teeth as lie in the path of the rib 47 are pointed, so that if the handle 6, with its pointer, is not brought to exactly the proper position to bring acharacter-type to the impression-point the action of the key-bar would be to shift slightly the index-wheel in one or the other direction as the rib 47 enters one of the radial slots in said wheel, and thus bring the types on the rings into proper registration with the tape.

When a section of strip of the length desired or which may be permitted by the arrangement of the apparatus has been embossed and it is desired to sever it from the main strip, either one of the lovers or handles 48 or 52 is depressed to operate the punch. This device (illustrated in detail in Fig. 11) consists of a punch 49 of the form shown and with two pins 50 to produce holes in the strip by which to attach it to any desired object and a die or female member 51. The punch 49 is arranged to slide vertically in guides and is connected with an arm 53, extending from a rocking frame 61, operated by either of the two levers 48 or 52. Lever 48 is mounted on the projecting end of a rock-shaft 54, which has two stationary bearings and 56. The other lever 52 is similarly mounted on a rock-shaft 57, having bearings 58 and 59. On

The under portion of the end of the I "levers 48 52 to out off the plate.

the inner ends of the rock-shafts 54 and 57 are cams 60, the shape of which is shown'in Fig. 3. The frame 61 hasashaft 62, carrying rollers 63, which are engaged, respectively, by the cams 60, so that when either lever 48 or 52 is depressed the frame 61 is tilted and the punch forced down through the die 51. Flat springs 64, secured at one end to the frame, force the frame 61 back to its normal position and withdraw the punch from the die when the handles 48 52 have been turned to their original position after being depressed.

65 66 are arms extending from shafts 54 and 57, respectively, and afford means for limit-- ingthe movements of the levers 48 52 by their engagement with lugs 67 68 on the main frame, as shown in Fig. 2, in which 69 is intended to indicate a strip of leather fastened to the arms 65 66 to serve as a buffer to relieve the shock when the handles are released and allowed to spring back under the action of the retractile springs 70.

To prevent the handles from returning too quickly to their normal position when released, dash-pots 7i, with their plungers connected with the arms 65 66, are also employed.

Figs. 8, 9, and 10 illustrate in different positions an auxiliary feed mechanism, which is shown in its operative relations in Fig. 2. The purpose of this device will be understood from a consideration of Fig. 5. In this figure astrip or tape is shown in the position which it occupies after the last letter of a name has been embossed. When the person operating the machine has embossed the final letter or character of a name, he depresses one of the The depression of either of these levers operates the punch, which shears off the plate, which then drops down through the lower type-wheel into the chute 72, by which it is delivered through an opening 73 in the case. This operation of lever 48 or 52 forces the punch 49 down through the die and then retracts it; but this alone would not advance the tape to a position Where it would receive an impresssion, and in order to efiect this advance an arm 83 is secured to shaft 54 in such a position as to bring a pawl 74 into engagement with the ratchet-wheel 33.

In Fig. 8 the relative positions of the pawl 74 and ratchet 33 when the lever 48 is in its normal position are shown. When the lever is pulled forward to its full extent, the parts assume the positions shown in Fig. 10. Then as the lever returns to its normal posit-ion itallows the punch to recede from the die just as the pawl reaches the position shown in Fig. 9 and comes into engagement with the ratchet. The further movement of the lever While the operation of the machine has been sufficiently explained to enable one to use it, the following directions for its manipulation will conduce to a better understanding of its nature and purpose. Assume thata name-plate has been embossed and out 01f. The machine would bein the condition shown in Fig. 2. If the user wishes to make sure that his plate is perfectly plain at starting, he may depress the lever 48 or 522, thus cutting off the short part fed forward after the last strip was severed and any other amount that mayhave been drawn out by improper manipulation of the machine, 850. On the return of the lever the tape is advanced to the printing position, as before described. The next operation would be to bring the pointer 6 over the first character to be embossed on the plate. The lever 20 is then depressed, which first forces the key-bar 43 into one of the radial grooves of the index-wheel and causes the type-rings to perfectly register. The further movement of the handle forces the plunger 11 upward and embosses a character by the types which are at the impression-point. Lever 20 is then released, the pointer moved to the next character desired, and the operation repeated.

When a space is required between any two characters, the pointer is moved to a point designated Space, which brings a blank portion of the type-wheels to the impressionpoint. The lever 20 is then operated as before, but the tape is merely fed forward space without being impressed.
